Position Transducers feature absolute quadrature output.

Press Release Summary:



Micropulse P-Style magnetostrictive linear positioning transducers offer selectable position resolution and pulse frequencies. Remotely triggered Burst Mode rapidly delivers accumulated pulse string to provide absolute position feedback upon request, eliminating need to re-home after power loss or cycle interrupt. Stroke lengths range from 51 mm to 3.6 m. Non-contact magnetostrictive technology features non-linearity of ±0.02% over 500 mm stroke.

Balluff's Micropulse P-Style LDT Version Now Offers Instant On-Request Absolute Quadrature Output


Balluffs Micropulse P-Style LDT version now offers instant on-
request absolute quadrature output for accurate position feedback without re-homing after power loss

Absolute positioning, selectable resolution and pulse frequencies, and easy-install profile form factor provide rugged alternative to glass scales, pots and LVDTs

FLORENCE, KY (July, 2003) - Balluffs proven P-Style profile-version Micropulse magnetostrictive linear positioning transducers are now available with on-request absolute quadrature output, giving designers a more rugged and reliable option to glass scales, potentiometers and LVDTs. Unlike ordinary incremental encoders with external "homing" switch, the Micropulse's P-Style absolute quadrature output features a remotely triggered "Burst Mode" that rapidly delivers an accumulated pulse string to provide absolute position feedback upon request, eliminating the need to re-home after a power
loss or cycle interrupt. The absolute quadrature output interfaces directly to standard encoder inputs (90° out-of-phase and A&B) and can operate in synchronous or free-running modes for maximum control system compatibility.

The flexible P-Style transducer with absolute output offers selectable position resolution (1, 2, 5, 10, or 50 m; 0.001. 0.0005 or 0.0001") and pulse frequencies (10, 208, 416, and 833 kHz). The P-Style works with both captive and floating magnet styles and is available in stroke lengths from 51 mm to 3.6 m to fit a wide range of motion control applications. Non-contact magnetostrictive technology provides extremely accurate, wear-free position feedback and features non-linearity of ±0.02% over 500 mm stroke.

The P-Style has an anodized aluminum housing which combines easy installation with rugged design and IP67 rating for reliable performance in sensor unfriendly environments. It reliably works in temperatures ranging from -40 to 185°F.

The Micropulse P-Style operates on 10-30V and is UL-approved and CE-rated. It is available with MS-style connector or 2, 5, 10, 15-m PUR cable-out versions for maximum installation flexibility.

Absolute quadrature output is also available on the Micropulse rod-style Z housing (operating at 24V or +/- 15V), which is ideal for precise positioning on hydraulic cylinders, injection molding machines, presses, woodworking machinery, packaging machines and leveling applications.
